Fixing my oil burner and a look at another eBay hand warmer.

The oil burner unit on my ancient heating decided to pack in just in time for a rather harsh winter spell. I'd tried getting it out for maintenance before, but it was seized into the boiler tightly. I had to open the full thing and knock it out gently from inside with a hammer.
The motor was attempting to turn, but was slow. I cleaned and lubricated the bearings, but will be getting a set of new ones.
While letting the unit run for a test I decided now would be a good time to make a video about the second catalyst hand heater that had just arrived. This time I did use the thermal camera as requested.
I think the phrase I was looking for was black body emitter.
